Hi, I'm new to this area and just purchased the 600w charger below. I connected it to a new 12V 100ah battery with 3x100w panels. The PV panels aren't the issue, as I tested them with another batt...

@Tom Stager  do you have a shunt inline to measure the wattage going into and out of you batteries? Your batteries may not be fully charged enough to make it through the night. If you have an ...

@Robert Thomas I would connect two in series then those two in parallel just to drop the amps in the wire to the controller. Lots of things to consider will any panels get shaded through out the da...

I charge batteries like this all the time. The bms should take care of the batteries for you. If one charges fast that the other the bms will shut it off and continue to charge the other. 

Sounds like a charging problem. How are you charging them?

Bonjour, il existe des panneaux de 400-480 watt. Leur voltage est de 36-40 volts. Votre mppt de 40 amp peut il prendre ce panneau? Et est il mieux de prendre 4 panneaux de 100 watt ou bien un seul...

Bonjour, j'ai acheter le mppt eco worthy 40 amp. je veux changer mes panneaux solaire trop faible, batterie de 280 AH. les gros panneaux genre 400 w et plus, ont de gros voltages, genre 40 volts...

Ok, I'm at the very beginning. I decided I want to try set up a solar system.  Started by ordering a dual tracking system with the 6-195w panels. I'm sure I will need more. The tracking seeme...

@Bastiieeen Au moment de la réception la tension était bonne.

Bonjour, Vous aviez testé la tension au moment de la réception ? elle à chuté à 0 ou c'est la première mesure que vous prenez ?

Bonjour, J'ai acheté une batterie LifePo4 il y a " mois sans jamais l'utiliser. Aujourd'hui, la tension aux bornes et de 0.00V. Que dois-je faire ? J'ai essayé de la recharger avec ...

Hey, I get it. I had a buddy who went through some stuff, and I didn’t even know what to look for. It’s hard not knowing what’s really going on, but you gotta educate yourself if ...

Hey everyone, I’m in a bit of a bind here. A friend of mine has been acting off lately, and I’m starting to worry they might be using. I want to learn what track marks look like so I ca...

Are you running them series or parallel or combined? I would series the panels to get as much voltage as the solar generator will allow. This will lower your amperage. Remember you can not allow th...

@Sam Carpenter  I bulk charge at 29.2 and float at 26.8. battery and utility are subject to how much you want to drain your battery. I switch to utilities at 26 volts and back to battery...

You have your 01 setting at sol and as you loose sunlight it will cycle off and on as the as it drops below and above the pv voltage threshold. I installed a pv contactor with a clock function to j...
